JOINT FOR GLASS PLATES.

Application filed December This invention relates to joints for plate glass windows, the object of the invention being to provide means by which it will be possible to join glass plates, mostly such as used in big show windows, in a more safe and attractive manner.

Heretofore various styles of joints for plate glass, as for instance, for show windows, have been used, all of which consist of metal. However, as those metal members usually tarnish and obscure the view of the observer, the appearance of a show window is affected, and a more attractive joint is greatly desired.

Certain difiiculties were encountered in the manufacture of joints from material, such as glass, which suggests itself for its transparency and low price. I have overcome those difiiculties by forming the clips holding the abutting'ends of the plates, and the other parts, in the manner illustrated in the accompanying drawings and described further below.

In said drawings,

Fig. 1 represents a front elevation of a pair of window plates with my new joint; 7

Figure 2 is a horizontal sectional view of my improved joint taken on the line 22 of Figure 1.

Figs. 3, 4 and 5 are perspective views of parts of my new joint; and

Figure 6 is a perspective view of a modified form of joint showing the parts in their separated relation.

Figure 7 is a horizontal sectional view of the form shown in Figure .6, showing the parts in their assembled relation.

By way of example I shall describe my new joint in connection with a joint made 4 of glass.

Referring to the drawings, 10 denotes the rear member in the form of a glass bracket bent in an angle of 90, or any angle as may.

be necessary, provided with holes 11 and 12 45 in a right angle to the smooth surfaces 13 and 14,.respectively, and preferably at an equal distance from the intersecting line 15 of the surfaces 13 and 14.

The smooth surfaces 13 and 14 of the glass 50 bracket 10 are to contact with the glass plates 16 and 17, respectively, in the manner illustrated by Fig. 2, the holes 18 and 19, respectively, being provided atsuch distancefrom the line in which the plates 16 and 17 55 abut, so .as to have the holes 11 and 18 on 18, 1922. Serial No. 607,469.

.oneside and .the holes 12 and 19 coaxially disposed in relation to each other.

Figs. {1 and 5 illustrate a screw and cap, respectively, which I use in connection with my new joint. 20 denotes a screw threaded bolt made of nickel or any other suitable metal, which at its one end has rigidly securedthereto the front part of the joint consisting of a ball-shaped glass button 21 with a. cylindrical glass stem 22 of slightly smaller diameter than that of the holes 18 and 19; the cap 23, with a female screw thread inside, may be operatively engaged with the bolt 20. The latter is inserted'on the one side through hole 18 and hole 11 of the glassbracket 10 held against'the plate 16, and on the other side a like bolt is inserted through holes 19 and 12 of the glass plate 17 and glass bracket 10, respectively, and by engaging said bolts 20 with cap 23, and turning the said cap as far as possible the glass'bracket 1O presses theplates 16 and 17 together, and owing to the correct distances and measurements as indicated above, the inclined edges of the glass plates t if) abut in line 20; the cylindrical stem 22, ow- I ing to its diameter being slightly smaller than that of the holes 18 and 19 and of a length corresponding with the thickness of the glass plate, fills entirely said holes with glass so that only the parts absolutely necessary to give the proper strength are of metal.

The surfaces of the glass button 21 and those of the bracket 10 are parallel to each other, and thus give a perfect and attractive joint.

In Figs. 6 and 7, I show a modified form of my invention. In the same the glass plates 16 and 17 do not abut directly, but are joined by a rabbet 24, made of glass, and having :two recesses or corners 25 and 26 into which the plates 16 and 17 are set. The rabbet 2 1 has a rounded projection 27 and coinciding substantially with the symmetrical aXis of said rabbet a screw threaded bolt 28 is rigidly secured therein. 29 is a bar, made of glass, having a curved surface 30 and plane walls 31 and 32. In its middle it has a bore 33 of such diameter to fit snugly over the screw threaded bolt 28, and on the side opposite to the curved surface 30it is provided with a rounded groove-34;. A nut 35 of such shape as to fit into the groove 3 1 is put over the bolt 28. It is evident from an inspection of Figs. 6 and 7 that the bar 29 with its walls 31 and 32 and the curved surface 30 registers with the opposite plates 16 and 17 and the'projection 27 or rabbet 24:, respectively, when the nut is turned so as to tighten the bar 29 unto rabbet24 e, and t0 thus tighten the glass plates between same.

walls 25 and 26 of the corners 25 and 26, respectively, are parallel'to the walls 3'1-and 32 of the bar and that all these surfaces are parallel to the respective "glas'seplates whereby aperfectly tight joint is effected.
